KIRKLAND — Surgery on Matt Hasselbeck's left shoulder made news this week, but the idea of operating on the injury was anything but new.
Hasselbeck suffered the injury at some point during the 2003 season and president Tim Ruskell said surgery was previously considered.
"It was a possibility last year," he said.
The Seahawks reached the Super Bowl, though, which meant Hasselbeck would have missed all of the team's offseason workouts if he opted for surgery.
Four to six months is a rough estimate for recovery, and Ruskell said he wouldn't write off the possibility Hasselbeck will be available for offseason workouts.
"He's not going to miss all the offseason because it's his left shoulder," Ruskell said. "He can still throw. He won't be able to take a [hit], but he wouldn't anyway."
Bruce DeHaven agreed to become the Seahawks' special-teams coach Friday, a move reported by The Dallas Morning News. He coached in Dallas the past four seasons and before that in San Francisco.
DeHaven replaces Bob Casullo, who held the job the past two seasons but was not under contract beyond 2006. Casullo accepted a job on Tampa Bay's staff earlier this week to coach tight ends.
That leaves the secondary coach as the only vacancy on the Seahawks' staff after Teryl Austin left for Arizona this week. The Seahawks hope to retain Dwaine Board as the defensive line coach.
Left tackle Walter Jones is among the Seahawks expected to undergo arthroscopic surgery in the offseason. He likely will undergo procedures on his knee and shoulder after participating in the Pro Bowl next month. The recovery time should not be extensive.
Other Seahawks expected to undergo arthroscopic procedures: S Michael Boulware (ankle, shoulder), RB Maurice Morris (ankle), OL Chris Spencer (shoulders) and OL Tom Ashworth (hip).
Tennessee asked permission to speak with Seahawks executives Mike Reinfeldt and Ruston Webster about the Titans' vacant general manager position.
Reinfeldt is the vice president of football administration and is responsible for the Seahawks' success in managing the salary cap. Webster is vice president of player personnel and has been in Seattle one year.
The Seahawks granted permission for both to talk to the Titans.
"I'd hate to lose either one of them," Ruskell said. "That would be crushing, but it reflects well on our organization. We've got good people here."
Tubbs hopeful for July
Defensive tackle Marcus Tubbs underwent microfracture surgery on his knee after going on injured reserve during the regular season. The team is hoping Tubbs will be ready when training camp begins in July, but that's not a sure thing. Tubbs was a first-round choice in 2004. He played five games this season.
• The Seahawks' training camp is expected to begin between July 23 and July 26 in Kirkland this year instead of Cheney. The team will play the Patriots in an exhibition game in Seattle on Aug. 2 and leave the following day for China, where the two teams play again Aug. 9.
